ELECTROLYTIC PROTECTIVE MEANS FOR CONDENSE'RS.

Application led November 3. 1927. Serial No. 230,767.

This invention relates to means of electrolytic protection for condensers and my 11nprovements are directed to a system oi' bus bars connected in the form of a grid, said bars being encased in insulation material and located in the respective headers of the condenser, and said bus bars being provided wlth a plurality of anodes that are removably attached thereto, to disperse the electrlcal current conveyed to said anodes throughout the body of Water that flows through said headers.

The grid composed of connected bus bars is connected to the condenser shell by supports that are suitably insulated therefrom and current is supplied to the bus bars b suitable electrodes. Y

In the drawings:

Figure 1 is a top view, partly in sectlon, of a condenser equipped with my improved system of connected bus bars and anodes detachably carried thereby.

Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1 through the header that is provided with the cooling water inlet and, outlet means. A

Fig. 3 is a vertical section taken on the line 3-3 of Fig. 1 through the header at the other end of the condenser and Fig. 4 is an enlarged partial View of connected bus bars showing-a detachable anode carried by one of said bars.

In said iigures let 1 indicate the tubular shell of a condenser, 2, 3, respectively the end plates thereof, 4, 5 respectively the opposltc plates carrying the series of water tubes 6,'7, and 8 the vertical partition separating the inflow and outilow compartments 9, 10 1ncluded in the header formed between plates 2 and 4, the compartment 9 having inlet 11 and the compartment 10 having outlet l2.

The condenser has the usual stay bolts 13, connecting header plates 2, 3, and is also provided with the usual steam inlet 14 and the outlet 15 for the product of condensation.

In the electrolytic system of protection' against deterioration of the condenser I provide in the compartments 9, 10, and in the compartment 16 formed between plates 3, 5, series of horizontal bars 17 and vertical bars 18 arranged in crossed relation, connected at their points of intersection, and lying in a vertical plane transversely of the condenser shell within said compartments respectively. The connected bars in eachcompartment thus form groups or grids adapted to carry a plurality of anodes for the dispersion of electrical current throughout the bodies of water iiowmg through said compartments. Since the grids in all the compartments are similar n cllilaracter the description of one will apply It will be noted in Fig. 4 that the bars 17 and 18 are in close contact to thus have electrical conductive relation, said bars being connected as by bolts 19 (only one example of the connecting means being illustrated). Also it will be seen that anodes 20 are secured to the bars at a-number of places thereon. In` Fig. 4 a single example is given of the means for attaching an anode to a bar, it bein,l ,0fv

shown as removably secured thereto by means `oi' a screw 21 that penetrates the bar and engages the anode, the anode lying in close electrical contact with the bar. The bars,l excepting where they contact with each other and with the anodes are entirely Wrapped or encased with insulation 22, so that said bars may not be themselves subject to the dei teriorating effect which would ensue if they were exposed, and so that the renewable anodes alone may be relied upon for the delivery of electrical current into the water compartment.

Suitable supports 23 of insulation material are secured to the condenser shell 1 and partition 8, the bars 17, 18 being connected to these supports to hold the grid rigidlyin its eii'ective position.

As means for delivering electrical current to the respective grids in their compartments I may employ an electrode 24 of suitable character, such for example as that shown and described in my application for patent filed' concurrently herewith, such electrode being insulated from the shell it penetrates, so that the flow of current must be from the anodes to the shell, thereby rendering the shell cathodic.

Variations within the spirit and scope of my invention are equally comprehended by eating electrical current to'said bars, anodes the foregoing disclosure. detachably carried by said bars, and insulat- I claim: I ing material that completely encases said 10A Electrolyt-ic protection means for conbars and their connecting meansrwhile leav- 5A densers comprising a system of 4connected in said anodes exposed. v metallic bars, insulating means for attaching. ew York, November 2nd, 3927. said bars to a condenser, means for commlin- ALEXANDER KRKALDY.
